    I have an HP desktop and I have been keeping it on 24 hours a day to record programs (I have Window Media Center with tv tuner). Now my computer shuts off during the day and it also shuts off when I use too much ram ie. using too many programs at one time. I know i have a problem with the fan because every time i try to turn it back on it says "System fan has failed. Service PC" How could I fix this?

Check whether the CPU fan or SYSTEM fan is working properly or not. If those are ok, go to BIOS and check see CPU fan speed & temperature.
eg: Your CPU should idle @ around 25°C if your room is 20°C or something like this.

If your computer keeps on shutting down after only a few minutes turned on .. chances are you are right. check the following:

check the fan of the power supply if it is spinning and check the air vent if it is clear of any obstruction like accumulated dust. if dust is heavy try using compressed air to free or rid of dust.

check also the heatsink of your processor and check if there is an accumulated amount of dust blocking the fan air from reaching the heatsink to cool your processor. use compress air again. check also if fan spin is giving enough air power to cool the processor.

Laptop or desktop computer overheating? Follow these tips to solve the problem

If you think your computer or laptop is overheating, follow these tips to solve the problem:

1) To confirm that overheating is the problem, install CPUID's Hardware Monitor (free download here):
Install Hardware Monitor and run it. The temperature of your CPU should be lower than 70 C for a laptop (lower than 60 C for a desktop PC). The temperature of your video card should be lower than 60, even if you're running a complex 3D game. The temperature of your HD depends on your manufacturer, but it should never be higher than 45 C (55 C for a 10,000 rpm driver)

2) To keep computer heat as low as possible, clean up your laptop or desktop regularly, removing dust and dirt. Remove the computer cover and use a compressed air can to blow the dirt out. Also, take care of verifying that the fan(s) move easily.

3) If you have a desktop computer, avoid placing it directly on the floor, since they will collect more dust thsi way. Place it on your desk. Also, avoid putting it inside any enclosure. Allow at least 3 inches between the sides of the case and a wall to allow plenty of air circulation.

4) If you have a laptop, avoid using it on top of any fabric (blanket, bed, pillow, etc). This blocks most of the airflow, causing overheating.

5) Laptops are not optimally designed for heavy gaming, which stresses your CPU and video card, producing very large amounts of heat. In other words, if your laptop overheats while playing 3d games, accept that this may be just normal for your machine... or play your games on a desktop PC.

6) Overclocking your CPU, GPU and/or FSB will produce much more heat than normal. To avoid the extra heat, do not overclock.

Read my other tips to keep your desktop or laptop computer running at top efficiency, including some tips about speeding up a slow computer.

Ensure that both the case fan and CPU fan are dust free and spinning. I think it could be overheating and then shutting itself off to prevent damage

Computer shutsdown unexpectedly

It sounds like it is overheating. Take the side off the case and see if your CPU fan works. Replace any fans that do not work or feel loose. And while you are at it, take a can of air and blow the dirt out of it.
Leaving it off overnight will not prevent it from overheating. A computer can overheat in a matter of seconds under the right circumstances.

I do not want to alarm you, but you may have overheated your computer. To check, think about where you kept your computer and what was the climate? constantly working in a hotter climate or even having worked on your computer for very long periods of time with out shut down, can cause over heating. If you did not, the fan or sink could have been broken or stopped working properly, there fore, overheating occurs. this wouldn't be your fault because you didn't know it happened. If you know how to take the casing off your computer, do so carefully and make sure to ground yourself. Then plug in the power cords, and turn on the computer, checking to see if the fan circulates. If it doesn't, then you have a fan and harddrive problem.

(Means, you can buy a new computer, yah!)lol (sorry, just trying to put a positive on the negative!)

My acer asipre 7720 series laptop keeps turning itself off with out warning

I have the same issue, I think it has to do with the computer overheating. The only way I have found to avoid this is to lower the power setting to normal usage, and to leave space between the back bottom vents and the surface the computer is placed on.

This is kind of like sticking a band-aid on a gaping wound though.
